WASHINGTON (CBSDC) – The Rev. Al Sharpton is being accused of falling nearly $30,000 behind on the rent for a D.C. office.

The lease at a downtown D.C. office space rented to Sharpton and the National Action Network is about to expire with Sharpton and Co. reportedly seven months behind on the rent, totaling more than $28,000 in debt.

The Washington Post reports that the space was rented out to Sharpton and NAN by the Conference of Minority Transportation Officials early last year. Julie Cunningham, COMTO’s president and chief executive, told the Post that NAN fell behind in debt after the first few months of prompt payments. She added that “friendly” letters sent to Sharpton and NAN board members fell on deaf ears.

“We were pleased that another group of similar status was coming in,” Robert Henry Prince Jr, COMTO’s board chairman, told the Post. “We didn’t know they wouldn’t be honoring their rental agreement.”

A rep for Sharpton, the prominent activist and MSNBC host, refuted the claims by COMTO that NAN was past due on the rent, telling the Post that NAN had signed a new lease in the building. But the two groups remain at odds over NAN’s alleged overdue rent payments.
